Stevie Nicks and Lindsey Buckingham finish each other's thoughts on social media, fueling Fleetwood Mac reunion rumours with "Frozen Love" posts.

Stevie Nicks and Lindsey Buckingham have sparked reunion rumors with seemingly coordinated Instagram posts. The musicians famously dated in the late ’60s and made the 1973 studio album “Buckingham Nicks.” Shortly after, Nicks, 77, and Buckingham, 75, joined Fleetwood Mac.

Fleetwood Mac’s Stevie Nicks and Lindsey Buckingham appeared to tease a potential reunion with cryptic Instagram posts. On Thursday, Nicks, 77, shared an Instagram post that read: "And if you go forward…," which may be referring to the lyrics from "Frozen Love," a song the band released in 1973.
